The content provides a tutorial on how to perform image conversion between different formats (JPG, PNG, WEBP) using Python’s PIL (Python Imaging Library) or the pillow library. Below is an analysis of the content while maintaining the original paragraph structure:
—
The article begins with an introduction to the PIL (Python Imaging Library) or pillow library, which is widely used for image processing in Python. The author highlights the importance of the `Image` class, which is central to the library. This class can be instantiated in various ways, such as loading images from files, processing other images, or creating images from scratch.
—
To demonstrate how to load an image from a file, the author provides a code snippet using the `open()` function from the `Image` module. The example shows how to open an image file (`test.png`) and display it using the `show()` method.

The article then introduces the concept of image conversion using the `Image.convert()` method. This method returns a converted copy of the image. The author explains that for the “P” mode, the method translates pixels through the palette. If the mode is omitted, the method automatically selects a mode that can represent all information in the image and palette without requiring a palette. The current version of the library supports conversions between “L”, “RGB”, and “CMYK” modes, with the `matrix` argument supporting only “L” and “RGB”.

The `save(fp, format)` method is also discussed, which takes two parameters: the file path (`fp`) where the converted file will be saved and the target file format. The author provides practical examples of image conversion, including:
